To roll back WaveSuite and NSP integration

Purpose

Perform this procedure to roll back the integration of a WS-NOC server and an NSP cluster, as may be required if the integration fails.

Note: You require the following user privileges to perform the procedure:

  • on each WS-NOC server station—root

  • on each WS-NOC main VM—mncmaintuser

  • on each NSP cluster VM—root or NSP admin

Note: release-ID in a file path has the following format:

R.r.p-rel.version

where

R.r.p is the NSP release, in the form MAJOR.minor.patch

version is a numeric value

Steps
 
1 

If WaveSuite has been deployed in an HA configuration, stop HA data replication as described in the WaveSuite HA User Guide.

2 

Log in as the root user on the WS-NOC’s NOC MnCMain VM.

3 

Edit the $MNC_HOME/config/bench/configuration.json file using a plain-text editor such as vi.

4 

Remove the "nsp" property from the "remoteAuthentication" => "active" field.

5 

Save the changes and close the file.

6 

Remove the below files from both the NOC and DRC servers.

  1. Enter the following:

    # cd $MNC_HOME/config/bench ↵

  2. Enter the following sequence of commands:

    rm -f activenspos.cfg

    rm -f nspOS.cfg

    rm -f nspca.tar

7 

On the WS-NOC’s NOC server, enter the following:

# sudo $MNC_HOME/setup/config.sh ↵

The WS-NOC is reconfigured.

8 

Enter the following to align the TLS certificates:

Note: The following command must be executed on the standby WS-NOC server, then an HA switchover should be performed, and the command should be repeated on the new standby server.

# sudo $MNC_HOME/setup/generateAndAlignCertificates.sh ↵
